Presumably part of the answer would be to remove any packages containing the word "mint", but you would need to make sure that this did not deprive you of needed functionality. For example, removing the packages mint-translations and mintupdate-debian might do so. Or you could decide that you might as well keep them. Apart from those two, the only "mint" packages on my system are linuxmint-keyring, mint-common and mint-info-xfce.

- remove apt.conf and apt.preferences files (if they exist) from/etc/apt. Apt "pinning" as it is called can screw with "Sid". You do not need apt.preferences to get the occasional package from "experimental";

- do not use any 'deb-multimedia' source other that "Sid", such as the Mint multimedia;

- remove apt.conf and apt.preferences files (if they exist) from/etc/apt. Apt "pinning" as it is called can screw with "Sid". You do not need apt.preferences to get the occasional package from "experimental";

Is this step also necessary in order to turn LMDE into debian testing?

I replaced all the content with the rule in point 6...because the default PIN of experimental repo is 100 and so updates are not shown in synaptic or with apt-get update (the default PIN of Stable, Testing and sid is 500).

patrik,those sources.list look right to track lmde+debian testing and yes, you should also in this scenario delete the preferences file.it serves a fine purpose with the vanilla sources.list but gives you more troubles than needed as soon as you leave the defaults.
